the linear density of a wire under tension t varies linearly from `mu_(1)` to `mu_(20`.Calculate the time that a pulse would need to pass one to the other.The length of the wire is l

A wire of length l is kept just taut horizontally between two walls.A mass m hanging from its mid point depresses it by delta .Calculte the time in which a pulse set up at one end will reach the other end . The mass of the wire per unit length of it is mu

A non-uniform wire of length l and mass M has a variable linear mass density given by mu = kx , where x is distance from one end of wire and k is a constant. Find the time taken by a pulse starting at one end to reach the other end when the tension in the wire is T .

A non-uniform wire of length l and mass M has a variable linear mass density given by mu = kx , where x is distance from one end of wire and k is a constant. Find the time taken by a pulse starting at one end to reach the other end when the tension in the wire is T .

The length of a metal wire is L_1 , when the tension is T_1 and l_2 when the tension is T_2 . The unstretched length of the wire is

A wire having a linear density 0.1 kg//m is kept under a tension of 490N. It is observed that it resonates at a frequency of 400 Hz. The next higher frequency is 450 Hz. Find the length of the wire.
